21641237 divided by 423 
We're looking to find how many times 423 goes into 21641237.

Moving on to step 1:
423 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 423

Step 2:
423 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Append the next digit (6) from the dividend to 21 and continue with: 216 / 423

Let's proceed to step 3:
216 divided by 423 is 0 with a remainder of 216.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 216, we get 216.
Bring next digit (4) of the dividend behind the 216 and repeat the process: 2164 / 423

Let's proceed to step 4:
When dividing 2164 by 423, we get 5 with a remainder of 49.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 2115 from 2164 and we're left with 49.
Include the next digit (1) from the dividend after 49, then repeat: 491 / 423

Step 5:
The number 423 fits into 491 1 times, leaving a remainder of 68.
The next digit of our result is 1. 
Result so far: 51.0
If we take 423 away from 491, we end up with 68.
Append the next digit (2) from the dividend to 68 and continue with: 682 / 423

On to step 6:
423 goes into 682 1 times with a remainder of 259.
Put 1 as the next digit of the answer. 
Result so far: 511.0
Subtracting 423 from 682 leaves us with 259.
Append the next digit (3) from the dividend to 259 and continue with: 2593 / 423

Moving on to step 7:
423 goes into 2593 6 times with a remainder of 55.
Record the quotient 6 as the next digit in the result. 
Result so far: 5116.0
If we take 2538 away from 2593, we end up with 55.
Append the next digit (7) from the dividend to 55 and continue with: 557 / 423

Going ahead to step 8:
557 divided by 423 is 1 with a remainder of 134.
The next digit of our result is 1. 
Result so far: 51161.0
The remainder is 134 after subtracting 423 from 557.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1340, and continue the process.

Let's proceed to step 9:
When dividing 1340 by 423, we get 3 with a remainder of 71.
Use 3 as the next digit of our solution. 
Result so far: 51161.3
Subtract 1269 from 1340 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 10:
The number 423 fits into 710 1 times, leaving a remainder of 287.
Put 1 as the next digit of the answer. 
Result so far: 51161.31
Subtract 423 from 710 to get 287.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2870, and continue the process.

Going ahead to step 11:
The number 423 fits into 2870 6 times, leaving a remainder of 332.
The number 6 becomes the next digit in our result. 
Result so far: 51161.316
Subtracting 2538 from 2870 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Let's proceed to step 12:
When dividing 3320 by 423, we get 7 with a remainder of 359.
Record the quotient 7 as the next digit in the result. 
Result so far: 51161.3167
Subtract 2961 from 3320 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Advancing to step 13:
423 can be fit into 3590 8 times, resulting in a remainder of 206.
Put 8 as the next digit of the answer. 
Result so far: 51161.31678
If we subtract 3384 from 3590, we get 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 14:
The number 423 fits into 2060 4 times, leaving a remainder of 368.
The next digit of our result is 4. 
Result so far: 51161.316784
If we take 1692 away from 2060, we end up with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Let's proceed to step 15:
423 can be fit into 3680 8 times, resulting in a remainder of 296.
Write down 8 as next digit of the result. 
Result so far: 51161.3167848
If we take 3384 away from 3680, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 16:
2960 divided by 423 is 6 with a remainder of 422.
The next digit of our result is 6. 
Result so far: 51161.31678486
Deduct 2538 from 2960 and we're left with 422.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4220, and continue the process.

The quotient of the division is 51161.31678486, and the remainder is 4.22e-07.
